I'm not sure. I started buying the NOS Realistic for nostalgic reasons. My brother has a GE mobile with the big meter on it and sounded real good so I thought I'd get me one. It's a nice one. I wanted to get a Royce because I've never owned one and got the 1-604. The guy who sold me the GE and the Royce has the 1-658 23 channel for sale. It's a beauty. Today's offerings don't get me going. My brother collects old radios and other stuff. He likes collecting mint and NOS items.
